A bantamweight (135 pounds) contest between emerging force Carson “Little Juggernaut” Beebe (13-2) of Schaumburg, Ill. and undefeated submission ace Joe Murphy (6-0) of Huntington Beach, Calif. has been added to the preliminary card as well, World Series of Fighting announced on Wednesday.

“We are excited to add another pair of match-ups to our preliminary card that will showcase a collection of the sport’s brightest up-and-coming athletes and future champions,” said World Series of Fighting President Ray Sefo.

“Since we launched our promotion last year, World Series of Fighting has made a commitment to building a roster of its own stars, so fighting as many potential future stars at our live events is critical in order to ensure that these athletes gain the necessary competitive experience to take their careers to the next level.”

The 26-year-old Gruetzemacher has been on fire since 2009, winning his last 10 fights. He has defeated each of his last seven opponents by way of (T)KO or submission, including four consecutive (T)KO victories.

Likewise, Sanders has notched nine straight wins. The 33-year-old has finished his last three opponents – two by way of submission and the third via TKO.

Beebe, the 24-year-old younger brother of bantamweight submission specialist Chase Beebe, is looking to return to the win column after he dropped a unanimous decision to Rolando Velasco in his last effort on Nov. 15, 2012. Prior to that, Beebe had reeled off seven consecutive victories.

The 25-year-old Murphy has been unstoppable since he made his professional debut with a first round (2:01) submission (armbar) victory over Orlando Aspericueta on May 1, 2009. Five of Murphy’s six wins to date have come by way of submission, including his last bout, an April 14 match-up with Tyler Weathers that Murphy won by way of armbar in the second round (2:56).
